You toss a coin three times. What is the probability that it will land heads all those three tosses ?

Answers

Answer 1
Answer: The probability would be 1 in 8, or 12.5%
Answer 2
Answer: - toss three times
- each time = 2 different possibilities
-3 x 2= 6 chances for heads or tails
6÷2 = 3
-3/6 chances = 50% chance

The probability is 50% or 1/2 to get heads once

to get all three times would be 1/8 or 12.5%

Answers

Answer:

(x -7)²

x = 7

Step-by-step explanation:

Given the quadratic function (polynomial):

x² - 14x + 49 = 0

The first term (x²) and the last term (49) are both perfect squares and the second term is the sum of the product of these two terms (-7 + -7 = -14):

(x - 7)(x - 7) = (x-7)²

1 gallon = 2.93
2 gallons = 5.86
3 gallons = 8.86

Therefore the correct table is D.

the dry cleaning fee for 3 pairs of pants is $18. what is the constant of proportionality. How much will the dry cleaner charge for 11 pairs of pants?

Answers

Answer:

Constant of proportionality is $6 for one pair and cost of dry cleaning 11 pairs of pants is $66.

Step-by-step explanation:

Dry cleaning fees is directly proportional to the charges of dry cleaning.

Cleaning fee ∝ Pairs of pants

Cleaning fee = k × Pairs of pants

where k is the proportionality constant.

If dry cleaning fee for 3 pairs of pants is $18 then from the equation given above

18 = k ×3

k = (18)/(3)=6

SO the equation will be Cleaning fees = 6×Pairs of pants

For 11 pairs of pants,

Cleaning fees = 6×11 = $66

Therefore, constant of proportionality is $6 for one pair of pants and cost of dry cleaning 11 pairs of pants is $66.

its 6$ for 1 pair of pants so for 11 pairs of pant's it is 66$
